A Long Island sex-education teacher has been arrested and charged with sexually abusing an 11-year-old student under the guise of demonstrating CPR in the classroom – and cops suspect he may have molested others.

Barry Goodman, 60, of Coram, the health teacher at the Plainview-Old Bethpage Middle School in Plainview, was charged with second-degree sexual abuse and endangering the welfare of a child.

Cops would not say if the alleged victim was a girl or boy.

Nassau County Sgt. Anthony Repalone said Goodman fondled the child through clothing on several occasions – in front of other kids – during a CPR lesson. Repalone asks that any other possible victims call police.

Goodman, a teacher since 1971 and also the girls swim team coach, could not be reached for comment.
